RUKO MGB set HSSCo VAP 35° M3-M12 machinedraadtapset

Threading a range of metric holes in tough materials can require multiple taps and frequent tool changes. This 7-piece machine tap set covers M3 to M12 coarse threads in one organized case, with a 35° spiral flute that pulls chips backward for efficient blind-hole work.

Who is it for

Machinists and maintenance technicians who tap unalloyed and alloyed steels, stainless steels, cast iron, and non-ferrous metals up to 1000 N/mm² tensile strength. Suitable for both through and blind holes.

Main features

• High-speed steel cobalt (HSSCo) with vaporized surface treatment for wear resistance.
• 35° right-hand spiral flute design for effective chip evacuation.
• Metric coarse thread sizes M3, M4, M5, M6, M8, M10, M12.
• DIN 371 (M3–M10) and DIN 376 (M12) shank standards.
• ISO 2 (6H) thread tolerance for standard fit.
• Supplied in a robust plastic case.

Tips

Use a suitable cutting fluid or coolant to extend tool life and improve thread quality. For blind holes, clear chips periodically to prevent clogging.
